MIR STATUS UPDATE
HR AMSAT NEWS SERVICE BULLETIN 117.01 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 27, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-117.01
According to official NASA reports, MIR 23 cosmonauts Vasily Tsibliev,
Alexander Lazutkin and Jerry Linenger continued the repair and
refurbishment of several MIR systems this week and began preparations
for next Tuesday's space walk by Tsibliev and Linenger.
The Elektron oxygen-generating system continues to operate normally. The
cosmonauts are continuing to use minor amounts of gaseous oxygen from the
Progress re-supply ship which is docked to MIR to augment Elektron's
output. Russian flight controllers plan to maintain this method of oxygen
generation for the station until the Shuttle Atlantis arrives with a new
Elektron unit in May.
The Vozdukh system continues to remove carbon dioxide from the Mir's
environment without interruption. The crew has been unsuccessful in
locating any leaks in a cooling loop in the Kvant-1 module that maintains
thermal conditioning for the Vozdukh, but it has not affected the
Vozdukh's performance. The cosmonauts confirmed that there are no
leaks in, around or behind the Elektron unit in Kvant-1. Work on the
cooling loop has been temporarily suspended.
Thermal loops in the Kvant-2 module also continue to operate normally.
By redirecting some of the internal ducting from Kvant-2 to the Mir's
Core module, crewmembers have been able to lower the temperature in the
base block by several degrees.
During the week, the crew successfully repaired leaks in the KOB-1
hydraulic loop in the Core module. After removing air from the system
and performing pressure checks, they reactivated the KOB-1 loop, which
continues to operate normally. The eventual reactivation of both KOB-1
and a companion cooling loop, KOB-2, should restore normal temperature
and humidity in the Mir core module. Conditions are reported, however,
to be comfortable in the main living quarters of Mir.
Mir remains in an orientation which is assisting to cool the Core Module.
This attitude also limits power availability because the Core module's
solar arrays are shadowed by the other modules. This is of no concern to
flight controllers.
On April 17, the crew resumed its normal exercise regimen.
The cosmonauts had performed only one hour of exercise a day
since April 10. Tsibliev and Linenger also participated in
the standard pre-spacewalk exercise effectiveness assessment.
Tsibliev and Linenger began moving EVA-related hardware to the
Kvant-2 airlock and checked out their spacesuits late in the week.
They will wear new Orlan spacesuits during Tuesday's spacewalk,
which is scheduled to begin at 11:50 p.m. Central time Monday
night. The spacewalk is expected to last almost 6 hours.
The spacewalk is designed to deploy environmental sensor packages and
radiation meters on the Mir's docking and Kvant-2 modules and to retrieve
two other experiments which have been collecting data on the effect of
micrometeorite impacts on the Mir for the past year. Due to Linenger's
work in repairing Mir systems and the time spent in spacewalk
preparations, some of the final science work for Linenger's tour of duty
was postponed until after the EVA.
The next Mir status report will be issued on Tuesday, April 29, following
completion of the spacewalk by Tsibliev and Linenger.

BID: $ANS-117.02
Word from NASA this week is that shuttle mission STS-83--cut short
in early April because of a fuel cell problem aboard the
spacecraft--will be re-flown in July with the Shuttle Amateur Radio
EXperiment--SAREX--aboard. The new mission will be dubbed STS-94.
The space shuttle Columbia prematurely returned to Earth April 8
without making any of the scheduled QSOs with 18 schools in the US,
the People's Republic of China, and Japan. Sixteen schools want to
arrange new schedules for the July mission, which will again carry
the microgravity science lab. Three hams were aboard STS-83: Jim
Halsell, KC5RNI, the mission commander; Janice Voss, KC5BTK; and
Donald Thomas, KC5FVF. The same crew likely will be tapped for
STS-94, set to launch on July 1 for a 16-day mission.
In the meantime, more QSOs of a scheduled round of ten MIREX school
contacts have taken place with Jerry Linenger, KC5HBR, aboard the
Russian Mir space station. Students at Holy Angels School in Dayton,
Ohio, got a chance to chat with Linenger April 21. The ground
station, W8DOZ, was running 35 W into a turnstile antenna. On April
23, students at Jerling Junior High School in Orland Park,
Illinois--a Chicago suburb--had a 10-minute contact with Linenger.
More than a dozen students got to speak directly to Linenger as an
audience of 800 students and 200 visitors looked on. Nearly 2500
students in other schools also got to listen in.
NASA reportedly intends to go ahead with plans for astronaut Michael
Foale, KB5UAC, to replace Linenger in mid-May. Foale, who
will arrive on the shuttle Atlantis, is scheduled to be replaced in
September by astronaut Wendy Lawrence, KC5KII. The last US astronaut
scheduled for a tour of duty on Mir is David Wolf, KC5VPF, in early
1998. The 11-year-old Mir space station eventually will be replaced
by the International Space Station--a cooperative venture between
Russia and the US.

NASA has announced that astronaut Jay Apt, N5QWL, is leaving NASA to
become the director of the extremely prestigious Carnegie Museum
of Natural History.
Jay earned his novice and technician licenses in 1990 while training for
his first spaceflight, STS-37. He's flown with SAREX on all four of his
spaceflights (STS-37, STS-47, STS-59, STS-79). He's an advanced class
ham, and also a volunteer examiner.
Some of the more unique contacts on those flights have included
Using SAREX as a contingency communications system when NASA's normal
communications loops were down due to a satellite ground station problem.
as well as using SAREX to talk to fellow astronauts training at Star
City in Russia. Jay also used SAREX via ground stations in Russia to

The seventh mission of the North Texas Balloon Project finally
took to the air at 10:14 a.m. on 19 April 1997 from the Cleburne, TX
Municipal Airport. Two hours later, it had a soft landing in a pasture
near Italy, TX and was recovered by NTBP personnel within 30 minutes. The
launch was delayed from its scheduled time of 9 a.m. by 1) local winds
aloft data not being available, and 2) unexpected burst of the first
balloon during inflation, the cause of which was unknown. But the
parachute spreader ring , swivels and woven tow line allowed a nice
easy descent.
The GPS experiment experienced two separate difficulties during the
flight. The Delorme Tripmate GPS receiver failed to maintain track
on enough GPS satellites to provide accurate altitude data. In fact,
the entire altitude data set was suspect and finally disregarded.
However, the Tripmate did provide accurate Latitude and Longitude data.
The other difficulty was related to the GPS beacon transmitter itself.
The HT's transmitter output power level dropped to near zero at 75
minutes into the flight. It has not been determined why the HT power
dropped, but extremely cold temperatures are a likelihood.
The FM crossband voice repeater was the highlight of the mission. The
following locations were able to hear and/or work through the balloon. In
Texas, Ft. Worth, Dallas, Houston, Plano, Irving, San Angelo, San
Antonio, Kerrville, Newberry; Clovis, NM; in Louisiana, Shreveport
and Bossier City; Wichita and Hays in Kansas; and last but not least
Vicksburg, Mississippi!
A great time was had by all operating through the balloon repeater.
In addition, the 35mm still camera took some great pictures every 3.3
minutes which lasted nearly the entire ascent leg. These photos will be
scanned and will be available for downloading within the next few weeks
at the NTBP web site:

The Dayton (Ohio) Hamvention is quickly approaching (May 16-18) and
AMSAT is looking for volunteers to help with the AMSAT-NA booth at the Hamvention.
For those unfamiliar with it, Dayton is a three day 'marathon' with
an immense amount of activity at the booth. AMSAT needs need folks
to volunteer for a 'tour of duty' during a portion of the Hamvention.
The AMSAT booth will be in the same location as previous years:
Booth spaces 445-448. Volunteers will help handle the myriad of
activities that typically occur at an AMSAT booth-handle transactions, take
memberships and renewals, answer questions, and serve as
a representative of AMSAT. Prior experience in representing AMSAT
at other hamfests is helpful but not required.
AMSAT-NA expects to have a very busy booth this year with a variety of updated
and new items:
1. Gould Smith, WA4SXM, has updated his "RS Satellite Operators Guide."
2. Keith Baker, KB1SF, has updated his "How to Use the Amateur Radio
Satellites" book.
3. Paul Beckman, WA0RSE, has a preliminary "Phase 3D Operators Guide"
that we expect to have available.
4. Gary Rogers, WA4YMZ, "Working the Easy Sats" will be printed and
included with new memberships (or available for a small donation).
5. An updated "AMSAT Frequency Chart" (laminated) will be available.
6. The "Amateur Satellite Resource Guide" will be available at the
Beginner's Forum (1200 Friday)
7. The latest in AMSAT 'fashion' featuring T-shirts (with pocket)
sporting the AMSAT logo.
The Booth itself will feature a number of interesting displays:
1. Tim Stookey, N8AHK, has built a 4' model of the Ariane 5 which
includes a 'storage tank' for placing cash donations to the Phase 3D Fund.
2. Eric Cottrell, WB1HBU, intends to demonstrate WISP at Dayton by
playing a video tape with the audio from a digisat pass into his TNC and
computer, allowing folks to see what actually occurs during a PACSAT
pass.
3. Terry Douds, WB8CKI, will have a video on continuos loop highlighting
recent activities at the Phase 3D Integration Lab
Please let Barry A. Baines, WD4ASW know if you can give a hand
during the Hamvention. Send Barry an e-mail and let him know :
1. What hours are you are willing to volunteer (Please volunteer for one
hour periods or multiples thereof) during each day that the commercial
exhibits are open. The commercial exhibits are open Friday 1200-1800,
Saturday 0800-1700, and Sunday 0800-1400. If you can help at various
times during the Hamvention, please provide a prioritization as to which
specified periods are best for you.
2. Include your name, callsign, and e-mail address in your message.
3. Indicate any special skills that would be helpful, such as
familiarity with specific products available through AMSAT, particularly software
such as WISP and NOVA. While AMSAT is looking for volunteers to help with the
'crush' of normal exhibitor activities, it would be helpful for Barry to know who
can assist in software demonstrations or answer particular questions
about various aspects of our hobby during a particular shift.
Barry intends to provide a tentative work schedule no
later than May 13 to those who have indicated a willingness to help.
Please stop by the AMSAT booth when you arrive at the Hamvention to
confirm your schedule or to change your work assignment if necessary.
Other Dayton items to keep in mind:
1. Don't forget the AMSAT dinner on Friday evening, 16 MAY, at the
Amber Rose Restaurant in old North Dayton. Contact Gerd Schreck,
WB8IFM@AMSAT.org. Packet WB8IFM@W8BI to register or for more information.
Cost is $19.50 per individual (includes dessert this year!)
2. Martha still has rooms available at the Homewood Suites in Fairborn,
OH. If you need a room for Dayton and would like to be added to the list,
contact Martha at AMSAT HQ: 301-589-6062. Be prepared to give her a
charge card number to reserve your room.
3. AMSAT will be involved with presentations during each of the three
days of the Hamvention. A Beginner's Presentation on Friday is scheduled
to start at 1200. This one hour forum is designed specifically for folks
who are not familiar with the satellite program and will provide information
on where to get help and what resources are available about the amateur
radio satellite service. If you know of anyone who would be interested
in this material, let them know of the forum in advance since it will
indeed start just as the commercial doors are opening.
Phase 3D and Manned Space will be covered during a Saturday afternoon
forum. Learn the latest status of P3D and how preparations are proceeding for
launch from members of the Phase 3D Team actually involved in building the
satellite.
In addition, Frank Bauer, KA3HDO, AMSAT's VP-Manned Space
Program, will moderate the discussion on SAREX and preparations for
Amateur Radio on the International Space Station. Past presentations
on Saturday have been standing room only and this year's discussion s
hould be just as popular. That's because NASA Astronaut Ron Parise,
WA4SIR, is tentatively scheduled to also address this forum IN PERSON
this year!
On Sunday morning, Ed Krome, K9EK, will give a talk on getting ready for
Phase 3D. This should be a popular topic, as Ed will outline ground
station considerations and provide tips on how to take advantage of
Phase 3D's variety of bands and modes.
Dayton is a unique opportunity to represent AMSAT to an extremely large
number of people. If at all possible, please consider giving a hand
during this event.

OZ1MY/Ib reports AO-10 has been FM'ing over the past few days.
Stacey Mills, W4SM, reports that the chances of
damaging AO-10 by uplinking during "FM'ing" are probably
remote. The caution mainly stems from a theoretical consideration.
AO-10's latching relays are set to the omni antenna and the transponder
is on in Mode-B configuration. This all turns out to be perfect since we
can't control the attitude, etc. Each time there's a power spike the
chance exists that the IHU could have a "seizure" and blurt out a pulse
to switch the antennas to hi-gain, or switch the transponder off.
Of course these spikes occur every time the satellite comes out of
eclipse, but the idea is to minimize the number of power spikes.
Occasionally spikes have "activated" the IHU in the past and caused the
beacon to send out nonsensical data rather than the current constant
carrier for short periods of time. ..and it also isn't exactly clear when
AO-10 switched to its omni antenna.

PACSAT (AO-16)
Russ Platt WJ9F, AO-16 Command Team , reports the digipeater on AO-16
has been on for the last couple of months. In regards to the 2.4 GHz
transmitter, it does continue to work although WJ9F has not been
leaving it on for an entire orbit due to its high current load on the
10 v bus.
The battery charging scheme on the micros is managed during sunlight
by adjusting the RCPSK transmitter power up or down to charge and
not overcharge the batteries since there's no way to turn the solar
cells off. The S-band transmitter does not have the ability to vary
its output so it is a high current draw throughout the orbit. In the
past, during Experimenters Days when the S-Band transmitter has been
turned on, they've had to scale back the output of the RCPSK transmitter
to levels that were difficult to receive. Even with these low levels,
the onboard software will still turn off the S-band TX if the Battery
voltage drops too low, which it sometimes did.
